Craters disappear in VBS2 when more rounds of DPICM is fired

There is a maximum number of craters which VBS2 will handle in a certain session. This is defined in a variable called MaxPermenantCraters in the VBS2NG.cfg file which could be found in the following path;

C:\Users\PCUSER\Documents\VBS2NG. This variable is by default set to 200. When the number of craters in the terrain becomes greater than this amount VBS2 clears all the craters which are less than the specified value (e.g: less than 200) in the terrain and creates the new craters if a new COF is carried out. By setting this variable to a desired higher value this issue can be solved.
